I just tried this patch a couple of hours ago and it does make the image a
lot clearer. Without it looks as if you are recoding at a lower bitrate
than you actually are.
Playback with viaslice now looks the same as playing back recordings with

I still have this weird problem with (I think) xv scaling with viaslice
that doesn't seem to get initialised properly. After I have played a movie
with mplayer (or xmame game, ...) the same scaling is used with live-tv or
playing back recordings. Play a 400x300 avi, afterwards only the upper
left corner of live-tv is visable.
Playing back a recoding in mplayer and then back to live-tv fixes things.

Anyone else noticed this?
